Product Description

Diamond grit edge holesaws have been specially developed for professionals that need to drill in extremely hard materials such as porcelain / gres / quarry tiles, cast iron or fibreglass where it is increasingly difficult to drill with conventional holesaws.; These holesaws guarantee excellent performance and superior life time even in the hardest of materials.; ¦¦ High quality; diamond grit is deposited and welded to the strip edge to give a strong bond and unbeatable durability.; The coarse grit provides fast and effortless drilling.; ¦¦ L arge dust; chambers ensure rapid dust removal and allow water into the cut to keep the teeth cool and extend life time.; ¦¦ Tough steel; holesaw body to give high wear resistance.; ¦¦ Thin wall design; meets less resistance for faster and cleaner drilling with less vibrations.; ¦¦ 4 drive pin holes; for easier arbor location

Drilling instructions

Use a cordless drill (make sure the hammer action is turned off). The optimum drilling speed is between 500 – 1000 rpm depending on the size of the holesaw.

The bigger the holesaw the slower the rpm. All the above materials with the exception of tiles can be drilled in a normal way with the pilot drill bit fitted to the arbor.

When drilling cast iron / ceramic tiles it is also recommended to use water as a coolant.

Drilling instructions for tiles Use a cordless drill (make sure the hammer action is turned off).

The optimum drilling speed is between 500 – 1000 rpm depending on the size of the holesaw.

The bigger the holesaw the slower the rpm.

When drilling tiles it is neccessary to use a template.

We recommend the use of our water cooling system but alternatively a template can be made from either wood or plastic with 5 – 10 mm thickness.

First cut a hole of the same diameter in either the wood or plastic template.

Remove the pilot drill bit from the holesaw arbor.

Fix the template over the tile by means of a clamp and fill the hole with water, if all the water runs out it may be necessary to place silicon or plasticine around the circumference of the hole between the template and tile to prevent the water leaking out.

Using the template as a guide for the holesaw (without pilot drill bit) start to cut into the tile ensuring a constant and plentiful supply of water to the holesaw tip.
